It seems like 2 regions can¡¯t be flushed and WALs Dir continue to increaseand Then I find this in client log:

INFO | AsyncProcess-waitForMaximumCurrentTasks [2014-06-03 15:30:53] - :Waiting for the global number of running tasks to be equals or less than 0,tasksSent=15819, tasksDone=15818, currentTasksDone=15818,tableName=BT_D_BF001_201406

Then write speed will become very slow.

After I flush 2 regions manually , write speed can back to normal only ashort while.

I still (highly)suspect that there is something wrong with the flushqueue(some entry pushed into it can't be poll out). ________________________________________发件人: sunweiwei [[EMAIL PROTECTED]]发送时间: 2014年6月3日 15:43收件人: [EMAIL PROTECTED]主题: forcing flush not works
